获取本机的所有IP,子网掩码(subnet mask)和默认网关

添加对System.Management的引用

using System.Management;
。。。
//获取IP,子网掩码(subnet mask)和默认网关
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
   ManagementObjectCollection nics = mc.GetInstances();
   foreach(ManagementObject nic in nics)
   {
                if(Convert.ToBoolean(nic["ipEnabled"]) == true)
    {
     Console.WriteLine((nic["IPAddress"] as String[])[0]);
     Console.WriteLine((nic["IPSubnet"] as String[])[0]);
     Console.WriteLine((nic["DefaultIPGateway"] as String[])[0]);
    }
   }
。。。

如果还需要其他信息参考 Platform SDK: Windows Management Instrumentation
